WATER-GOVERNOR FOR BOILERS.

Specification of Letters Patent.

Patented July 16, 1907'.

Application filed October 15 1906. Serial No. 339,047.

To all whom it may concern:

Be it known that I, ARTHUR S. VINCENT, a citizen of the United States,residing at Toppenish, in the county of Yakima and State of Washington,have in-' vented certain new and useful Improvements in Water-Governorsand DangerAlarms for Steam-Boilers; and I do declare the following tobea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to a combined water governor, and danger alarmfor steam boilers, whether stationary or movable.

.The object of the invention is in a ready and practical manner to givean audible alarm in case the water in a boiler sinks below apredetermined level and also to insure the automatic operation of thepump in the event of such an emergency.

With the above and other-objects in view, as will appear as the natureof the invention is better understood, the same consists in the novelconstruction and combination of parts of a combined water governor anddanger alarm for steam boilers, as will be hereinafter fully describedand claimed.

1n the accompanying drawings forming a part of this specification, andin which like characters of reference indicate corresponding parts,thefigure is a view in elevation of a boiler equipped with the improvementsof the present invention.

Referring to the drawings, 1 designates a boiler of any preferred type,and 2 the steam dome thereof.

Arranged within the boiler at a point below the steam dome and withinthe dome are two horizontally-disposed guides 3 and 4 in which works arod or bar 5 that carries at its lower end a float 6, and at its upperend a conical valve 7 that is designed normally to close one end of apipe 8 that leads to the feed pump. The valve 7 is disposed near theupper portion of the dome, thus to insure the passage of dry steam tothe dome, and carries at its ripper end a whistle or other suitablealarm 15. The weight 11 normally holds the valve 13 in the positionshown, thus to cut off any escape of steam to the pipe 14 and thence tothe whistle, but in the event that the water in the boiler sinks below apredetermined level, the lever 10 is struck by a striker or arm 16 thatis carried by the rod 5, thereby unseating the valve 13 and causing thealarm to be sounded. At the same time that the valve 13 is unseated, thevalve 7 is also unseated, thereby to allow steam to pass to the steampump and start it to working, thus to supply water to the boiler untilthe proper level is reached. When such level is restored, the valve 7,by reason of the lifting of the float 6, Will cut off the supply ofsteam to the pump, and thus stop its operation. As the float 6 lifts,the striker 16 will move out-of engagement with the arm 10 and thusallow the valve 13 again to resume its seat.

By the arrangement of the mechanism shown, an engineer will always benotified by the whistle 15 when the water is low in the boiler, so thatin the event that the pump does not start to Work from any cause he willbe properly informed, and will be enabled to prevent any catastrophewhich might otherwise result if he depended wholly upon the automaticstarting of the pump, by the lowering of the level of the water in theboiler. Generally, however, dependence may be placed upon the startingof the pump, and its proper operation by the dropping of the float 6.

I claim:'

The combination with a boiler, of transversely-arranged guides disposedwithin the steam dome and at a distance belowthe same, arod working inthe guides and carrying at one terminal a float and at its otherterminal a valve, a steam pump connection communicating with the domeand with which the valve coacts normally to close the passagetherethrough, a pipe entering the boiler and carrying .a whistle, awhistle-controlling valve, a counterpoised lever supported by the lowerguide and with which the whistlecontrolling valve is connected, and astriker carried by the float rod and operating to unseat the last-named"alve when the float drops by the lowering of the water in the boiler.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

ARTHUR s. VINCENT.
